Determine the values of x , if any, at which each function is discontinuous. At each number where f is discontinuous, state the condition(s) for continuity that are violated.

40. x Details ......" 40. A curve and a point are graphed on the x y coordinate plane. The horizontal axis is labeled: x. The vertical axis is labeled: y. The curve goes down and to the right in the second quadrant from (negative 3.5, 12) to (0, 1) and then enters the first quadrant and goes up and to the right through (3.5, 12). The point is plotted at (0, 0). 20- + 1 if x * 0 f (ac) = nshot 0 if x = 0
